6 Technical Description

6.1 PCI Bus Support

The S1D13A05 does not have on-chip PCI bus interface support. The S1D13A05B00C
uses the on-board PCI Bridge FPGA to support the PCI bus.

6.2 Direct Host Bus Interface Support

The S5U13A05B00C is specifically designed to work using the PCI Bridge FPGA in a
standard PCI bus environment. However, the S1D13A05 directly supports many other host
bus interfaces. Connectors H4 and H5 provide the necessary IO pins to interface to these
host buses. For further information on the host bus interfaces supported, see "CPU
Interface" on page 13.
Note

6.3 S1D13A05 Embedded Memory

The S1D13A05 has 256K bytes of embedded SRAM. The 256K byte display buffer address
space is directly and contiguously available through the 18-bit address bus.

6.4 Adjustable LCD Panel Negative Power Supply

Most monochrome passive LCD panels require a negative power supply to provide
between -14V and -24V (I
the S5U13A05B00C board. VLCD can be adjusted using potentiometer R21 to provide an
output voltage from -14V to -24V, and is enabled/disabled using the S1D13A05 general
purpose signal, GPO0 (active high).
